20100067555 | TUNABLE OPTICAL SUPERCONTINUUM ENHANCEMENT - A method and apparatus for providing optical supercontinuum. The method comprises creating a spectrally narrow phase feature within a supercontinuum spectrum produced from a laser pulse that has been subjected to supercontinuum generation, thereby producing a modified supercontinuum spectrum, and propagating the modified supercontinuum spectrum through an optical waveguide that is suitable for supercontinuum generation, thereby further modifying the modified supercontinuum spectrum. The method may include modifying the modified supercontinuum spectrum by increasing its energy in a vicinity of the phase feature. | 03-18-2010 |
20100178052 | OPTICAL SIGNAL TO NOISE MONITOR - An optical noise monitoring method and monitor, the monitor comprising an optical transmitter for receiving at least a portion of an optical signal, a device arranged to extract a reflected optical signal comprising a portion of the optical signal back-reflected by stimulated Brillouin scattering in the optical transmitter, and a photodetector for receiving the reflected optical signal. The optical transmitter can scatter the optical signal by stimulated Brillouin scattering. | 07-15-2010 |
20130209097 | Photonic Monitoring For Optical Signals - This invention concerns real-time multi-impairment signal performance monitoring, [n particular it concerns an optical device, for instance a monolithic integrated photonics chip, comprising a waveguide having an input region to receive a signal for characterization, and a narrow band CW laser signal. A non-linear waveguide region to mix the two received signals. More than one output region, each equipped with bandpass filters that extract respective discrete frequency bands of the RF spectrum of the mixed signals. And, also comprising (slow) power detectors to output the extracted discrete frequency banded signals. | 08-15-2013 |

20140036500 | ILLUMINATED STRIPE AND ILLUMINATED STRIPE SYSTEM - An illuminated stripe includes light-emitting light sources and a member for conducting current to the light sources and a casing part. The light sources and/or the member for conducting current to the light sources are at least in part surrounded with the casing part. At least a part of the casing part includes a first substance, and at least a part of the casing part includes a second substance. | 02-06-2014 |
20140122018 | METHOD AND SYSTEM FOR OBSERVATION - A system and method for monitoring presence, location, movement and/or attitude of one or more objects in a monitored space. The system includes sensors, which are arranged to certain part of the monitored space, e.g. to floor, wall or ceiling. The sensors are distance measuring ultrasonic sensors which produce measurement results and the system is configured to determine presence, location, movement and/or attitude of an object based on the measurement results. | 05-01-2014 |
